SHELL-EJECTOR FOR BREAKDOWN GUNS.

SEECFIC/ATION formingpart of Letters Patent No. 665,941, dated January15, 1901.

Application filed September 26, 1899. Serial. No. 731,738. (N model.)

To all whom t may concern.'

Be it known that I, ELMER E. STUBBs, a citizen of the United States,residing at Jonesborough, in the county of Craighead and State ofArkansas, have invented a new and useful Ejector for Breech-LoadingShotguns, of which the following is a specification.

This invention relates to a new and useful improvement in an automaticshell ejector and extractor for breech-loading breakdown guns ofpreferably the double-barrel haminerless class.

One object of this present invention is to provide an automaticshell-ejector, which is also an extractor, which will be set or cockedready to eject a shell upon the closing of the gun and not upon theopening of the gun, as is usual in devices of this character, and bywhich construction no additional Work is imposed upon the opening orbreakdown action, leaving the same to perform its usual function ofcooking the gun without requiring the application of additional force.

Another object of this invention is to provide a combined shell ejectorand extractor whereby should the ejector mechanism fail to properlyperform its designed function of ejecting or throwing out the emptyshell, which is possible in any ejecting device under adverseconditions--such, for instance, as the swelling of the shells in dampweatherthe positive movement of the extractor will force the shellsufficiently out of the barrel to enable the operator' to grasp andwithdraw the same by hand.

Another object of this invention is to provide means whereby when thegun is opened the ejector will operate only upon the shell or shellswhich has or have been fired or ex- 4o ploded, leaving the unexplodedshell orshells in place in the gun.

Another object of the invention is to provide means whereby the ejectormechanism will be positively operated upon the opening of the gun toinitially start the shell, after which the fired shell will be ejectedby the impellent action of a spring whose energy is stored when the gunis closed.

The essential features of this invention reside, first, in the novelconstruction and arrangement of the ejecting mechanism proper;

second, in the novel means employed for operating the ejector proper;third, in the novel means employed whereby only the eX- ploded shell inthe chamber of the gun will be ejected when the gun is opened, or, inother words, if both Bring-hammers have been tripped, which means thatboth shells have been exploded, both of said exploded shells will beejected when the gun is opened; but if neither of the hammers has beentripped neither of the shells has been exploded and the opening ofthegun will not eject either of the unexploded shells, and where onehammer only has been tripped only one shell will have been exploded, andthat only will be ejected upon the opening of the gun, leaving theuneXploded shell in its chamber; fourth, in the novel construction ofthe divided ejector and extractor; fifth, in the novel construction andarrangement of the divided ejector and extractor stop-bolt; and,finally, the invention consists in the novel construe tion, arrangement,and combination of the several parts, all as will hereinafter bedescribed and afterward pointed out in the claims.

I attain the objects heretofore referred to by the mechanism illustratedin the accompanying drawings, in which- Figure l is a longitudinalsectional View through one of the locks and a portion of one of thebarrels of a hammerless breakdown breech-loading gun provided with myimproved automatic shell ejector and extractor as the same appears whenthe gun is in a closed position and the hammer tripped after firing.Fig. 2 is a similar View to that of Fig. l, showing the gun in an openor broken position and the hammer cocked. Fig. 3 is a detail view of thebreech end of the barrels, illustrating in position thereon the dividedejector employed in carrying out my invention. Fig. 4 is a sideelevational view of one of the members of the divided ejector employedin carrying out myinvention. Fig. 5 is a plan View of both members ofthe divided ejector employed in carrying out my invention. Fig. 6 is aplan view of a portion of a gun and a portion of my improved ejector andextractor, together with ahorizontal sectional view of a portion of thebarrels. Fig.

IOO

is a similar view to that of Fig. 8, with the' addition of the ejectorthereto, and illustrates the parts as they appear when the gun has beenfired and broken.

In the drawings, A indicates the frame, B the barrels, C the fore-endiron, which carries the barrels and which is pivoted to the forward endof the frame A, as is usual, D the hammers, E the sears, F the triggers,'and G the mainsprings, all of said parts being practically of the usualand well-known construction.

The general construction and operation of a double-barrel hammerlessbreech-loading gun of the breakdown type are so well known that adetailed description of the same is deemed unnecessary; but for thepurposes of introducing in this description myimproved shell ejector andextractor I will explain that when the gun is broken after one or bothhammers are tripped the tripped hammer or hammers are cocked or movedrearwardly until a notch or shoulder thereon rides over and cooperateswith the forward ends of the sears, which retain the hammers in suchposition against the tension of springs until the trigger or triggers ofthe gun are pulled.

The operation of opening the gun not only cocks the hammers, as abovedescribed, but also releases the ejector mechanism and allows the sameto perform its function of ejecting the exploded shells; but thisopening movement does not cock or set the ejectors, they having beencocked or set by the closing movement, which is an advantageous feature,for the reason that no more force is required to open a gun equippedwith my improved ejector than would be required in opening a gun havingno ejector, as I do not employ the opening movement of the gun to bothcock the hammers and set the ejector, that work being divided,respectively, between the opening and closing of the gun. In otherwords, the opening movement of the gun releases the ejector and expelsthe empty shell, and the ejector is then reset or cocked, ready for thenext ejectment by the closing movement of the gun. For the sake ofclearness I will describe but one lock. While there are two representedin the drawings, they are substantially the same, and this is due to thefact that the drawings, as before stated, represent a double-barrel gun;but each lock acts independently of the other, and the operation of themechanism would be substantially the same as a single-barrel gun.

In the forward portion of the frame of the gun and in vertical alinementwith each ham mer is a cylindrical bore a, which is arranged on such aslant relative to the barrel of the gun that its axis will pass,preferably, below the pivot-point of the hammer D and above thehinge-pin ot' of the barrels. This bore is sufficiently deep to receivea suitable length of the coiled spring G, and axially in line with andopening into this bore a is a bore a" of smaller diameter, which bore a"is formed through the frame A.

H represents a plunger, preferably formed with a rearwardly-openingconcavity h,which is arranged in the bore a and has secured to itsforward end a rod h' and around which rod and interposed between theforward end of the plunger and the stock at the forward end of the borea is arranged the expansible coiled spring Gr. The hammer D is providedwith an extension d below its pivot-point, and pivotally secured to saidextension is a dog or pusher-bar D", which protrudes into the concavityh and rests against the plunger This hammer D is provided with ashoulder, which `when the hammer is forced to its cocked positionengages and is retained by the forward end of the sear E, and when inthis position the pusher-bar D' has pushed the plunger and its carriedrod forwardly against the tension of spring G, said movement alsocausingtheforward end of the rod h' to project beyond thepartially-cylin d rical end of the frame A, the object and purpose ofwhich will hereinafter be described.

Arranged in advance of the pivot-point of the barrel and secured to thefore-end iron C is a block I, upon and within which is mounted themechanism employed for actuating and cooperating with the dividedejector and eX- tractor J.

The block I is provided with a verticallydisposed slot t', in which aremounted two pivoted tu mblers K K', two pivoted levers,which I Willtermtumbler-sears, L L', and two leaf-springs M M', which are preferablyconnected at one end to receive the securingsorew.

Directly above the rear portion ofthe block I and slidingly mounted inthe rear portion of the fore-end iron C is what I will term thecooking-bar N, the forward end of which is designed to rest against thesuitablyeurved rear faces of the tu mblers K K', while the rear ends ofsaid cooking-bar rest in a forwardly-opening concavity 0 of what I willterm the extractor-arm7 o', arranged on a sleeve O, located around thehingepin and between the forked end of the frame A.

`P represents a cap-piece screwed or otherwise fastened to the upperrearward portion of the fore-end iron, which is provided with a slot orrecess p, which slot or recess is directly above the tuinblers K K' andallows the same in their rearward movement to pass thereinto, as shownin Fig. 8. Formed in the IOC IIC

lower rearward portion of this cap-piece P and opening into the slot orrecessp are two parallel grooves, in which are arranged two parallelslidable ejector needles or bars Q Q', the forward ends of which touchand are in the path of movement of the tumblers K' K', while therearward ends touch or abut against the forward ends of the dividedejector and extractor J. This divided ejector and extractor, which isshown more clearly in Figs. 3, 4, and 5 of the drawings, is constructedof practically two semicylindrical rodsjj, with their dat faces restingagainst each other. Arranged on the rear end of each of the rods jj areheadsjwj", said heads being provided with suitable shoulders jm forreceiving the rim or bead of the shell or cartridge, as is usual inextractors of this type. Suitable guide-pins jf are also provided foreach of the heads j"j' forobvious reasons. These semicylindrical rods jj are provided with recesses 7'6 and j7, which when the ejector andextractor members are both in either their extreme forward or extremerearward positions are in alinement with each other; but when only oneof the rods is moved rearwardly said recesses are out of alinement, asis illustrated by dotted lines in Fig. 5.

The forward ends of the divided extractor are reduced to form on theiradjacent faces shoulders, as shown in Fig. 5, against which the arm 0/operates when the gun is being opened. The needle-bars Q and Q operateto move the two parts of the ejector or extractor independently of thearm 0', and, as shown in Fig. 6, said needle-bars are arranged on eachside of the arm 0. This divided ejector and extractoris mounted in thebreech portion of the barrels of the gun in the usual mannerbyallowingthe cylindrical rod formed of the two semicylindrical membersto enter a suitable bore located below and midway between the chambers,suitable bores being also provided in the end of the breech forreceiving the guide-pins R represents a pin or bolt which passes throughthe lug between the barrels and is designed to pass through the slotformed by the united recessesjj and is designed to arrest thesemicylindrical rods in their rearward movement, as is clearlyillustrated in Figs. 1, 2, and 6 of the drawings.

The block I is provided upon its sides with suitable longitudinalgrooves t" 2", in which are bars S S, respectively held in theirrearmost positions against the partially-cylindrical forward end of theframe A by springs s s, interposed between their forward ends and abearing-block s". These sliding bars S S are so proportioned that theirrear ends 3" are offset laterally from the bar proper, and their extremerear ends are formed slightly convexed or curved, which enables them inthe rearmost position of said bars to snugly iii thepartially-cylindrical forward end of frame A, said ends 5 being also inalinement with the rods h', the ends of which are also formed with acurve of the same radius as the partially-cylindrical end of the frameA. Y

T indicates rockers or projections formed on the under sides of theslide-bars S S,which are designed to coperate with the projections l andZ on the tumbler-sears, respectively. The block I is secured to thefore-end iron by means of a suitable screw V, (see Figs. 8 and 9,) whichpasses through the concave portion of the block which is next adjacentthe hinge` portion of the gun. It is of course understood that lateralmovement of this block I is prevented by the anges u, which engage eachside of the fore-end iron.

The operation of my improved shell ejector and extractor is as follows:As has been stated before, the ordinary operation of the breakdown gunshown in the drawings is that when either or both hammers are trippedthe breaking or opening movement of the gun will reset or cock thetripped hammer or ham mers. When the hammers are cocked, as shown inFig. 2, the plunger-rods h are projected forward and the slides S and Sare held in a forward position, the rockers or projections T occupyingpositions in advance of the projections Z and l on the sears for theejector-tumblers. Being in advance of said Sear projections, the searsfor the ejector-tumblers are in engagement with the respective tumblersto the extent that the sears are in the paths of the shoulders on thetumblers; but there is sufficient clearance between said shoulders andthe rear ends of said sears to permit the free movement of the sears.When the gun is closed, as shown in Fig. 8, the cocking-bar N is inengagement with both tumblers, forcing them slightly beyond a positionwhere their shoulders will engage with the sears L and L', and in thismanner all strain is removed from the ejectors proper, so that saidejectors will not crowd the breech of the gun. When one of the hammershas been tripped, as shown in Fig. 1, the controlled plungenrod h' isretracted, s0 as to permit the cooperating slide-bar S to moverearwardly, which movement forces the sear L to make an idlevibration-that is, said sear is depressed so that its end passes out ofthe path of the tumbler-shoulder, said sear end again returning to aposition in the path of the shoulder on the ejector-tumbler. Assumingnow that the gun is broken, the first movement is to force theextractor-arm 0 against the shoulders in the forward ends of the dividedextractor, so as to positively move said extractor rearwardly. The con?tinued movement of breaking the gun next cocks the tripped hammer, whichresults in forcingvthe cooperating slide S forwardly and in so doingdepresses the sear L out of the path of the shoulder on the tumbler K.As the cocking-bar N is now in a position to be projected into therecess o the moment that IOO IIO

tumbler K is released, it delivers an impacting blow against theneedle-bar Q, which in turn engages with the left-hand side of theejector and moves the same rearwardly beyond the position to which ithad been moved by the action of the arm 0'. This quick hammer-like blowdelivered by the tumbler K forces the left-hand side of the ejectorrearwardly until it is arrested by the bolt R operating in the recess jsthereof. The above description applies where the left barrel only hasbeen fired, and it will be obvious that as the right barrel has not beenfired the slide S occupies its forward position, so that the scar L' isin a position to arrest the tumbler K and prevent said tumbler frommoving under the action of its spring M. In fact, when either of theslides S or S' occupy their forward positions before the gun is brokenneither ofthe tumblers K orK wil be ltripped, but the arm 0' will alwaysact to positively move the parts of the ejector to 'force the same andtheir carried shells rearwardly a slight distance, so that they can begrasped in the hand and taken out, if desired. It is only when theslides S or S occupy a rear position resulting from tripping theircontrolling-hammers that the opening movement of the gun will vibratethe ej ector-tumbler sears and release said tumblers. When the rightihand barrel is red, the empty shell from that side of the gun will befirst moved positively by the arm o' and then ejected when the tumbler Kis tripped. The positive movement above referred to also operates tomove rearwardly the uniired shell, but not to eject it.

From the above it will be seen that when` either one or both barrels ofa gun are fired the ejector mechanism will operate to throw the emptyshell from the gun. When the shells are not tired, however, only theextractor will work to place the unfired shells in position to begrasped by the hand of the operator, if desired.
